Common Scams

Social Security Scams

Scammers pretend to be from Social Security Administration and try to get your social security number or money.

Phone Scams

Remember, we will never call and ask you for a one-time passcode or any other sensitive information. This is against our security protocols, which are designed to safeguard your personal information.
If you receive an unsolicited call from someone claiming to be from TOPCU, exercise caution. Always feel free to ask questions or simply hang up and call us back through our official contact number at (520) 881-6262

Phishing Scams

Scammers use email or text messages to trick you into giving them your personal information.

Unemployment Benefits Scams

Imposters are filing claims for unemployment benefits.

“Am I safe, or am I being scammed?”

Know the red flags

The most common types of scams will target you through fake emails, text messages, voice calls, letters or even someone who shows up at your front door unexpectedly. No matter which technique the scammer uses, you may be:
  • Pressured to send money
  • Threatened with law enforcement action
  • Told to purchase gift cards and provide codes as a form of payment
  • Asked to deposit a check that overpays for something you’re selling, then send the difference elsewhere

The best ways to avoid being scammed


Don’t respond: If you’re not 100% certain of the source of the call, email or text, then hang up the phone, don’t click on the link in the email and don’t reply to the text message.
Don’t trust caller ID or answer phone calls from unknown numbers: If you recognize the caller ID but the call seems suspicious, hang up the phone. Phone numbers can be easily spoofed to appear to be from a legitimate caller.
Don’t give out your information: Never provide any personally identifiable information unless you’re absolutely certain the person and reason are legitimate. Remember: TOPCU will never ask you to send us personal information such as an account number, Social Security number, one-time passcode,  or Tax ID over text, email or online.
Research and validate: If the individual or organization seems suspicious, make sure the request being made is legitimate by calling the organization through an official number from their website or consulting with a trusted family member or friend.

Identity Theft Resources

According to the Federal Trade Commission (FTC), Arizona has ranked high on the list of all states in identity theft. Identity theft occurs when a criminal steals another person’s personal information to take on that person’s identity. Identity theft is much more than misuse of a Social Security number—it can also include credit card and mail fraud. Knowledge and awareness are key ingredients in arming yourself against identity theft.

The FTC Consumer Information site is a one-stop national resource about identity theft, providing current information and practical tips to help you deter, detect, and defend yourself from fraudulent activities. Learn more at the FTC online resource center.

You can also find additional information on Identity Theft from the Arizona Attorney General’s Office.
